CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 525,549, datedseptember 4, 1894.

Application filed April 18, 1894. Serial No. 508,008. (No model.)

To' all whom it may concern.'`

Be it known that I, JOHN C. HURLEY, a citizen of the United States,residing at Fairhaven, in the county of Whatcom and State of Washington,have invented a new and usef ful Oar-Coupling, of which the following isa specification.

The rinvention relates to improvements in car couplings.

The object of the present invention is to simplify and improve theconstruction of car couplings, and to provide anefticient one capable ofcoupling automatically, and of being readily uncoupled without goingbetween cars.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings: Figure 1 is a side elevation of two car couplingsconstructed in accordance with this invention, and shown coupled. Fig. 2is a plan view of thesame. Fig. 3 is a detail perspective view of one ofthe draw-heads. Fig. 4 is a longitudinal sectional view of the carcoupling. Fig. 5 is a detail perspective view of one of the jaws. Fig. 6is a horizontal sectional view, the parts being arranged as shown inFig. l. Fig. 7 is a transverse sectional view, taken through one of the.jaws.

Like numerals of reference indicate corresponding parts in all theiigures of the drawings.

1 designates a draw-head mounted on a car 3, and provided withacushioning spring, and having a shoulder 2 arranged in advance of thedead-wood of the car. The draw-head is provided with a transverse recessor groove 4, extending horizontally on the upper face of the draw-headand vertically at one side thereof, and receiving a pivoted jaw 5, whichis composed of an angular shank 6 and upper and lower laterally oisethooks, arranged to engage similar hooks of a corresponding car coupling.The angular shank consists of a the hooks. The depending vertical arm ofthe shank 6 is located in the vertical portion of the recess 4, and theother arm of the shank extends vertically from the top of the-drawheadin advance of the shoulder 2, and at the adjacent terminal of the recess4. The shank 6 is provided at its angle, adjacent to the lower end ofthe upper arm, with a perforation 7, through which passes a pivot orpintle 8, which is also received in perforations 9 of the draw-head,located at the upper terminal of the L-shaped recess 4.

The upper laterally oiset hook 9@ has its front face 10 beveled, and isprovided with a shoulder 11 and the lower laterally olset hook 12 has acorrespondingly beveled front face 13, and is provided with a shoulder25. These hooks extend horizontally from the terminals of the angularshank, and are adapted to be engaged by corresponding hooks; and whentwo ears come together for coupling, the beveled facesl of the hookscontact, and the latter are forced laterally, the jaws swinging on thepintles 9, to permit the shoulders of the hooks to engage one another.The depending arm of the angular shank is longer than the upwardextending arm, and the lower hook 12 may be slightly heavier than theupper one, and by these means the jaw 5 is maintained normally in properposition for automatic coupling.

The draw-head is provided in Yrear of the jaw 5 with a depending detent14, which may be constructed integral with the draw-head,

or otherwise as desired. The outer face of the detent` is beveled, andits inner face 15 forms a shoulder or stop, which is engaged by a hookor catch 18 of a rod or shaft 16 journaled in suitable bearings 17 at thback of the lower hook 12. The hook or catch 18 is arranged at the innerend of a rod or shaft 16, which is provided at its outer end with ahandle 19, and which, after the jaw has engaged the hooks of acorresponding jaw for coupling, is adapted to be partially rotated tocarry the catch 18 into engagement with the shoulder or stop of thedetent, whereby the jaw is securely locked rigid with the drawhead, andits hooks are retained against lateral swing.

The operation of uncoupling may be performed from either side of a carby turning the rod or shaft 16 to disengage the catch or hook 18 fromthe draw-head; the rods or shafts of two draw-heads project fromopposite sides of the same, and either may be turned in the manneraforesaid, after which the operation of unconpling may be completed byswinging the hooks of one jaw laterally out of engagement with the otherjaw. The catch 18 and the rod 16 also contribute weight to the lowerhook l2, to form a gravity catch of the pivoted jaw 5.

The draw-head is provided at its front end with vertical ribs or flanges20, one of which is provided at its center with a horizontal recess 21,and has a vertical coupling pin perforation 22 receiving a coupling pin23, which is provided with a head 24, and which is adapted to engage theordinary construction of link to enable the draw-head to be coupled withthose cars having the ordinary pin and link car couplings.

It will be seen that the car coupling is simple and inexpensive inconstruction and positive and reliable in operation,thatit is capable ofeffecting the operation of coupling automatically, and that theoperation of uneoupling may be readily performed without going betweencars.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

What I claim is- 1. In a car coupling, the combination of a draw-head,and a jaw pivotally mounted on the drawhead and disposed transverselythereof, and comprising an angular shank having a horizontal portionextending across the top of the draw-head and provided with verticalarms one of which extends upward from one end of the horizontal portionand the other depending from the opposite end of the horizontal portionat the adjacent side of the draw-head, and forwardly extending hooksarranged above and below the drawhead and projecting from the arms ofthe shank, substantially as described.

2. In a car coupling, the combination of a draw-head, and a jawpivotally mounted 011 the draw-head at one side thereof and comprising ashank extending across the top and one side of the drawfhead, and thehooks 1ocated above and below the draw-head and carried by the shank,substantially as described.

3. In a car coupling, the combination of a draw-head provided with atransverse recess extending 'across the top and one side of it, and ajaw having a horizontal and a vertical portion arranged in the recess ofthe drawhead and pivoted thereon, said jaw being provided with upper andlower hooks disposed yopposite each other and located above and belowthe draw-head at the top and bottom of the jaw, substantially asdescribed.

4. In a car coupling, the combination of a.v draw-head provided with arecess, a jaw pivoted in the recess and capable of swinging therein, anda hook revolubly mounted on thet jaw and arranged to engage thedraw-head and capableof being turned ont of such engagement, whereby thejaw may be held against swinging and be released for uncoupling,substantially as described.

5. In a. car coupling, the combination of a draw-head provided with arecess extending across the top and one side of it, a jaw having ahorizontal and a vertical portion and arranged in the recess and pivotedtherein at one end of the horizontal portion, coupling hooks carried bythe jaw, and a securing hook journaled on the jaw and arranged to engageand disengage the draw-head, substantially as described.

6. In a car coupling, the combination oa` .To v

operating rod journaled on the jaw and oarrying a catch arranged toengage the stop of the draw-head, and adapted to becarried out of suchengagement by turning the rod, substantially as described.

In testimony that I claim the foregoing as g5 my own I have hereto aixedmy signature in the presence of two witnesses.
